This might be a weird question, but I was wondering if there might be an add-on to convert Ponyfinder to "Ponyfinder: Exodus"?

I was thinking of using the Glutton Creeper Games Exodus RPG weapons and vehicle rules as a base and leaving the magic as it is. I'm not certain if this would be an alternate history of Everglow where the humans and two-legs didn't arrive or if it's yet another planet where the quardupedal races ended up. I of course just really really REALLY want a Fallout: Equestria game that uses familiar rules.

Oh I know there are many out there that are simple, but I don't need to learn yet another ruleset that I will only use for a few game sessions.

Anyway. Just hoping to get little pastel Ponies with guns and insane radioactive monsters.
